DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring first to FIGS. 1-1B, an embodiment of a heating/cooling article for wearing apparel 10, consistent with an embodiment of the present invention is shown. In this embodiment, the heating/cooling article 10 includes the following main components: a wearing apparel product 12 having a plurality of interior pockets 14 (as best seen in FIG. 1A) located thereon, into which a plurality of removable inserts 30 (as best seen in FIG. 1B) may be inserted. In this embodiment, the wearing apparel product 12 comprises a jumpsuit, but other forms of wearing apparel products could be used, including but not limited to shirts, jackets, pants, shorts, socks, stockings, hats, caps, helmets, headbands, wristbands, sweatbands, military apparel, wet suits, dive suits, firefighter uniforms, and the like. (A few examples of such embodiments are shown in FIGS. 2-2A and FIGS. 5-9A).

Preferably, the interior pockets 14 are positioned in such a manner that when the wearing apparel product 12 is worn, individual interior pockets 14 are situated over different areas of a person's body for which it may be desired to provide heating and/or cooling. In this embodiment, six interior pockets 14 are employed, but more or less pockets could be used, as desired, with pockets 14 being located over different body extremities. Also in this embodiment, the interior pockets 14 have a top opening 16 to allow the removable inserts 30 to be inserted. It may be desired to provide a closure at the top of the interior pockets 14, such as a zipper, button, snap, Velcro, or the like, to help secure the removable inserts 30 in place within the interior pockets 14.

Referring specifically to FIG. 1B, removable inserts 30 are inserted in the interior pockets 14. The removable insert 30 in this embodiment is substantially elongated, but other shapes could be used for the removable insert 30, in order to accommodate various forms of wearing apparel products, as best seen in FIGS. 2A, 5A, and 6A. As best seen in FIG. 3, in this embodiment, the removable insert 30 comprises an outer layer 32, a gas valve 34, and a valve system (not shown). The outer layer 32 encloses a gas that is released when the valve 34 of a compressed gas cylinder (not shown) contained within the insert 30 is pierced by a valve spike 40 (as best seen in FIG. 4 and in FIGS. 2A, 5A, 6A, 7A and 9A). The release of gas from the compressed gas cylinder results in cooling of the removable insert 30 which, in turn, results in cooling of a person wearing the wearing apparel product 12 containing the removable inserts 30. The valve system (not shown) prevents gas escaping from the removable insert 30 when the compressed gas cylinder is pierced by the valve spike 40 and also after the empty compressed gas cylinder is withdrawn. Another valve system (not shown) may be provided for exhausting the gas before refilling the removable insert 30 with the gas. Any gas that is non-flammable and non-toxic may be used, but carbon dioxide is a preferred gas in the compressed gas cylinder. It may be desired to couple a compressed gas cylinder to the wearing apparel product 12, or to other forms of wearing apparel products, including but not limited to shirts, jackets, pants, shorts, socks, stockings, hats, caps, helmets, headbands, wristbands, sweatbands, military apparel, wet suits, dive suits, firefighter uniforms, and the like.

Referring to FIG. 4, the valve spike 40 is preferably made of a durable material, such as metal or plastic. While the valve spike 40 is shown as being separate from the cylinder, the valve spike 40 could be located in an upper portion of a removable cap that can be inverted and placed in position, or there may be other means for accomplishing the piercing of the cylinder.

In another embodiment, the removable insert 30 comprises an outer layer 32 and an inner core (not shown), comprised of a reactive material, enclosed by the outer layer 32. The core is activated by exposing the removable insert 30 to air or by breaking an inner bag (not shown) of the removable insert 30 and shaking the removable insert 30. In one example, the core comprises a combination of iron powder, water, activated carbon, vermiculite, salt, wooden powder and PURGE™ natural mineral powder, obtainable as a product named BEYOND BODI HEAT® (made by Okamoto Industries Inc., Japan). When the removable insert 30 is exposed to air, the removable insert 30 heats up exothermically to maintain an average temperature of 104° F. for 12 hours. The removable insert 30, comprising BEYOND BODI HEAT® as the core, is disposed after use, but requires no outside source other than exposure to air to activate the product.

In another example, the core (not shown) comprises an inner bag (not shown) separating ammonium nitrate and water. On breaking the inner bag and shaking the removable insert 30, the ammonium nitrate dissolves in water, resulting in endothermic dissolution with resulting cooling of the mixture of ammonium nitrate and water. THERA-MED® (Thera-Med, Inc., Waco, Tex., U.S.A.) is an example of a commercially available ammonium nitrate based product. The removable insert 30, comprising THERA-MED® as the core, is disposed after use, but requires no outside source other than breaking the inner bag and shaking the removable insert 30 to activate the removable insert 30.

In yet another example, the core (not shown) comprises a gel pack (not shown). The removable insert 30 comprising the gel pack core may either be placed into a refrigerator for cooling or into a microwave oven for heating. TRU-FIT™ I.C.E./HEAT (distributed by BD™ Consumer Healthcare, Franklin Lakes, N.J., U.S.A.) is an example of a commercially available Gel Pack consisting essentially of a high heat capacity solution of a polyacrylamide in water. The removable insert 30, comprising TRU-FIT™ I.C.E./HEAT as the core is reusable but requires an outside source to activate the product.

The removable inserts 30 either cool or warm various parts of a person's body. A warming removable insert 30 may assist in easing muscle pain. In addition, a warming removable insert 30 may be of particular value to a person performing various activities, such as hiking, mountain climbing, playing sports, laboring, or the like, in a cold climate. A cooling removable insert 30 may also assist in easing muscle pain and/or treating swelling. In addition, a cooling removable insert 30 may be of particular value to, for example, a hiker, soldier, laborer, or athlete in a hot climate.

Referring now to FIGS. 8-8A, an embodiment of a heating/cooling article for wearing apparel 80, consistent with an embodiment of the present invention is shown. In this embodiment, the heating/cooling article 80 includes the following main components: a wearing apparel product 82 and a length of tubing 84 (shown in FIG. 8A) coupled thereto. Preferably, the tubing 84 is located on the interior surface of the wearing apparel product 82. It may be desired to couple the tubing 84 to the exterior of the wearing apparel product 82. In this embodiment, the tubing 84 branches out several times while passing throughout various areas of the wearing apparel product 82. It may be desired for the tubing 84 to form a loop. A gas valve 34 may be attached to the tubing. A heating/cooling gas may be released when the valve 34 of a compressed gas cylinder (not shown) is opened, or when a seal on the cylinder is pierced by a spike 40. The spike may be coupled to a portion of the tubing 84. In this embodiment, the wearing apparel product 82 comprises a military combat suit, but other forms of wearing apparel products could be used with the tubing 84, including but not limited to shirts, jackets, pants, shorts, socks, stockings, hats, caps, helmets, headbands, wristbands, sweatbands, jumpsuits, wet suits, dive suits, firefighter uniforms, and the like.

The release of gas from the compressed gas cylinder (not shown) results in heating or cooling of the wearing apparel product 82 which, in turn, results in cooling of a person wearing the wearing apparel product 82 containing the tubing 84. As shown in FIG. 8A, the tubing 84 preferably defines a plurality of weep holes 86 (or dispersion holes) for dispersing the gas toward the interior of the wearing apparel product 82. The weep holes 86 may be positioned at uniform angles along the tubing 84 or at alternative angles to allow for multidirectional dispersion of the gas within the interior of the wearing apparel product 82. The number of weep holes 86 may be increased or decreased as desired. It may be desired for the tubing 84 to not include any weep holes 86.

The wearing apparel product 82 may be recharged with the gas as needed to continue heating or cooling the wearing apparel product 82. Any gas that is non-flammable and non-toxic may be used, but carbon dioxide is a preferred gas in the compressed gas cylinder. It may be desired to couple a compressed gas cylinder to the wearing apparel product 82, or to other forms of wearing apparel products, including but not limited to shirts, jackets, pants, shorts, socks, stockings, hats, caps, helmets, headbands, wristbands, sweatbands, wet suits, dive suits, firefighter uniforms, and the like.
